Microelectrode Recording (MER)

Microelectrode recording (MER) uses electrical current (5-100uA) at a very high frequency (300Hz) to precisely identify the surgical site for implantation of the deep brain stimulator (DBS). This technique was pioneered at Johns Hopkins, and is endorsed by the Task Force on Surgery for Parkinson's Disease of the American Academy of Neurology Therapeutic and Technology Assessment Committee.

Because not all brains are the same, the information obtained from MER gives an accurate target for final DBS placement. The microelectrode allows our team to visualize and hear the neuronal activity from different areas of the brain to identify specific structures based on the unique patterns of neuronal activity.

Our team in the operating room will move some of your joints or may ask you to move your arms, hands, feet and/or legs, to modulate the activity in the sensorimotor portion of the brain to target the precise location that is involved in that movement. This allows the surgeon to precisely map the target area.
